Should I let my potatoes flower?

Why do farmers cut the tops off potato plants?
The desiccation of the potato canopy is a critical part of the crop’s management, enabling growers to stop bulking when tubers reach the desired marketable size and promote skin set.
What to do when potatoes start flowering?
Flowering just means that the vines are mature enough and have enough leaf area to start forming tubers. It doesn’t mean the tubers are ready to harvest. Until they reach mature size, your potatoes should be watered regularly though the summer, from 1 to 3 inches of water per week, as needed.
What does poking holes in a potato do?
“It pokes holes in the skin, which allows steam to escape. Otherwise, they could explode—it doesn’t happen all the time, but it happens every once in a while. The potato is full of water it’s trying to turn to steam, or water vapor. The skin acts like a pressure vessel.
How do you maximize a potato yield?
When the potatoes have sprouted and grown foliage about 8” tall, you should begin “hilling” the plants by mounding the fluffy soil on either side of the trenches up around the stems of the plants. As long as there is some foliage sticking out they’ll keep growing, and the more you hill, the more potatoes you’ll get.
Should I cut the tops off my potato plants?
Potatoes are hardy plants requiring little pruning as they grow. Once you see small flowers appear on the plants, the potatoes can be prepared for harvesting by trimming the stalks above the ground. The earlier you trim, the smaller the potatoes will be, but small potatoes are sometimes desirable.
Do you cut the tops off potato plants?

Why are my potato plants so tall?
Potato plants can grow too tall when they have been given too much fertilizer, especially when it’s rich in nitrogen. Nitrogen can encourage potato plants to develop more than usual, and this is evident in the overgrowth of their tall green shoots above the ground.

You’ll also risk stressing the plant and its precious root system, so although you could try replanting it, the plant might not thrive. Wait too long, and your potatoes may get damaged by frost, or begin to sprout, crack or rot underground. It’s enough to drive you starch-raving mad!

How tall should potato plants be before covering?
Potato plants should be “hilled” when the plants are 8 to 12 inches tall (Figure 7). Figure 7: When the plants are 8-12 inches tall they should be hilled to keep tubers covered and prevent greening. Mound the soil to a height of 3 to 6 inches and approximately 12 to 15 inches from the base of the plant.
Can you hill potatoes after they flower?
The Short Answer
Potatoes need to be hilled as the stems grow vertically for the first month or two in the spring, until flowering. Tuber formation begins when the plants start to flower. If the plants are starting to die back then hilling potatoes at that time will not produce any more benefit.
